Title: High speed multiecho mr imaging method
Inventor: KURISU MIZUMOTO
IPC: A61B5/055
Filed: 1989-07-13
Abstract: PURPOSE:To obtain at least three MR signals which are weighted by the different lateral relaxation time in the pulse repetition time by applying a gradient magnetic field having the less integration value than the time integration value of the lead gradient, in the reverse direction to that of the lead gradient. CONSTITUTION:A high frequency rotary magnetic field RF applied in the direction perpendicular to a static magnetic field is generally applied with alpha deg. pulses. In the slice direction, a slice gradient for exciting only the spin on a specific plane is applied, while in the phase direction, the gradient magnetic field (first warp gradient) having each different amplitude is applied, and the phase information in the phase direction is obtained. The first warp gradient reduces the integration value of the area of the gradient magnetic field per cycle which is applied in the phase direction to zero by applying the second warp gradient which has the equal magnitude and the same direction to the first warp gradient after the last echo is generated, and the spin is put into stationary state. Therefore, though restricted by the effect of the inequality of the static magnetic field, longitudinal relaxation time T1, and the lateral relaxation time T2, the lead gradient is spread, and the gradient of the succeeding negative half wave in sine form is increased, and at least three MR signals can be obtained in the pulse repetition time tau.
